"Email communication with our customers and regulators is constant, and email encryption is an essential component to the protection of our customers' privacy and our company's reputation," said Randy Behrens, Director of Information Technology for American Bank and Trust. "We initially selected ZixCorp because of its leadership in the financial industry and its capability to provide secure, transparent email. We continue to find value in ZixCorp's solutions, especially in its reliability and its assistance with easy communication with regulators."

ZixCorp Email Encryption is offered through Software-as-a-Service architecture and has a proven history of reliability. Its reliable services are the solution of choice for all federal financial regulators, including members of the FFIEC, making the exchange of encrypted email easy between American Bank and Trust and its regulators.

"ZixCorp's email encryption is a great benefit when exchanging information in the course of conducting routine business with our primary federal regulator, the Office of the Comptroller of the Currency," said Behrens. "We seamlessly and easily share many confidential documents. More importantly, we have high confidence in the information security features protecting our clients' privacy through our use of ZixCorp."

Through its ZixGateway service, ZixCorp is the only vendor to offer transparent email encryption. ZixGateway automatically scans outbound email and encrypts sensitive content based on corporate policies. Any recipients who use ZixGateway automatically receive encrypted email transparently, without any extra steps or passwords.

"Our reliable service and unique advantages, such as transparent email encryption, enable us to maintain the loyalty of valuable customers like American Bank and Trust," said Rick Spurr, ZixCorp's Chairman and Chief Executive Officer.
